Notable bits:
Next year, Huawei and Samsung plan to introduce more competitively priced foldable phones, and other Android manufacturers are expected to follow suit, driving accelerated expansion in the foldable phone market.
Recent reports from industry insiders suggest that Huawei’s development of a triple-foldable screen phone is progressing smoothly and may be ready for launch before March next year. It’s expected that two triple-foldable screen phones will be introduced in 2024.
Supply chain sources have also revealed that Samsung is planning to bring foldable phones to the mid-range market next year, further reducing price barriers and making foldable phones more accessible to a broader range of consumers.
This is unrelated to your point but you’ve hit in an interesting idea. If they were willing to dedicate a significant part of the body to the camera there could be a breakthrough. If they were willing to make the lens much bigger (like, 2 inch) and/or go in most of the phone thickness it would give it better optical qualities.
